低温种质库主要用于保存以种子为主体的植物种质资源。该文对中国主要低温种质库采用的保温墙材料和厚度、地面架空层高和抗震设计等建筑技术,机组运行控制方式、制冷方式、制冷剂和除湿方式等制冷除湿技术,以及种子架、干燥设备等进行了调查和分析。根据调查结果,就有关建好低温种质库的关键技术问题,如库房面积、高度、墙壁、围护结构、干燥系统、种子架以及制冷除湿等方面提出了建议。
Low-temperature germplasm bank is mainly used to preserve seed germplasm resources. In this paper, building materials and thickness of heat insulation wall, floor height and seismic design of main low temperature genebank in China, refrigeration and dehumidification technologies such as unit operation control mode, refrigeration mode, refrigerant and dehumidification mode, Drying equipment, etc. were investigated and analyzed. According to the survey results, suggestions are put forward on the key technical issues related to the construction of low-temperature germplasm bank, such as the area of the storehouse, the height, the wall, the enclosure structure, the drying system, the seed rack and the refrigeration and dehumidification.
